What differences are there between covalent and allosteric modification?
The metabolism of fatty acids is regulated in the short term by allosteric modulators, covalent modification and _________. Group of answer choices: A) Fluctuating nutrient availability B) Energy demands C) Changes in gene expression D) Hormones E) A, B and C are all correct
Explain two mechanisms of proteins regulation. Include one mechanism that uses covalent modification (include enzymes that modify in your explanation) and one mechanism of allosteric regulation. Give specific examples of each.
Describe how the opposing processes of glycogen breakdown and synthesis are reciprocally regulated by allosteric interactions and the covalent modification of key enzymes.
7. Provide ONE example of "allosteric control" and ONE example of "covalent control that occurs in glycogenolysis, OR glycogen synthesis (your choice!) and BRIEFLY describe how this control responds to changes in the concentrations of metabolites in the cell. (6 points) a. Allosteric control: b. Covalent control:
Metabolism can be regulated via Group of answer choices regulating synthesis of particular enzyme. allosteric effectors. feedback inhibition. covalent modification of enzymes. All of the above.
- Part A Why is covalent modification used to regulate the activity of an enzyme? Match the words in the left column to the appropriate blanks in the sentences on the right. Make certain each sent Reset Hel can be activated or deactivated as needed Covalent modification is useful to regulate the activity of enzymes because it is ; enzymes by addition or removal of a covalently bonded group (e.g., a phosphate group). irreversible can only be activated reversible can...
